A Reckless Nerd

What if Tris was different then anyone else in the school. She goes to dauntless high where the rest of her friends go. In the middle of the school year a mysterious boy pops into the equation; his name is four. What we know is that he will fall for Tris. But what we don't know is which side will he fall for. Her Badass side, or her nerdy side. Or could it be both? Badass and a nerd?
